Title: Automobile braking system - is double circuit type with quick acting fail safe action on failure of one
IPC: B60T17/22
Filed: 1973-08-24
Abstract: Four brake cylinders (10AV), (10AR) act on the vehicle wheels. A source of fluid pressure (11) is taken to the brake cylinders by separate circuits (12A), (12B) under control of pedal device (13). Source (11) is a pump (14), with inlet (15) connected by line (16) to a reservoir (17) outlet (18) being connected to circuits (12A), (12B). There are also reservoirs (20A) (20B).

Title: Reconstituting ham etc. in compression mould - in which faces move in to apply pressure in two directions simultaneously
IPC: A22C7/00
Filed: 1974-02-22
Abstract: A machine is claimed for reconstituting processed meats in partic. boned ham by a period of compression in a mould cavity. The machine has a mould cavity in the form of a horizontal tunnel of rectangular cross-section, the top and one end of the tunnel being the front faces of piston-type platens on pistor rods of fluid powered cylinders on axes intersecting at right angles; the end of the tunnel opposite the horizontal axis cylinder is adapted as a loading/unloading door and once the cavity is loaded and the door closed, both platens are advanced simultaneously to compress the contents in two directions at once. The machine pressing is effective in about 2 hrs. per cavity load compared with about 12 hrs. previously necessary, representing a reduction of about 80% in the number of moulds necessary for a given output. Not only is manual handling of moulds reduced, but power ejection after compression obviates a further, difficult, manual operation.

Title: Measurement method for real gas imperfection coefficient - gas is decompressed and temp. stabilised for measurement wrt. perfect gas law of variation
Inventor: DELAJOUD PIERRE
IPC: G01N7/00
Filed: 1975-07-11
Abstract: The gas is placed in a first vessel of a volume (VI), and its pressure P1 measured. Gas is then decompressed by connection of this vessel to a second vessel of volume (V2) in which initial pressure is P2. A time is allowed for temperature stabilisation, and then pressure P3 in this vessel combination (2) measured. Values of P1, P2 and P3 are used for the imperfection coefficient Z computation. Pressure P2 is given the value of atmospheric pressure, or a value near it. The ratio of volumes V2/V1 is given a value between P1/P2 and 2P1/P2. Coefficient Z is computed by the method of consecutive approximations requiring the knowledge of only the values of P1, P2, P3 and V2/V1.
